Patented June 27, 1933 UNITED STATES PATENT OFFICE GEORGE E. WORTH, 0F MIDDLETOWN, CONNECTICUT, ASSIGNOR TO THE WORTH HILL- ING COMPANY, 1110., OF MIDDLETOWN, CONNECTICUT, A CORPORATION OF CON- NECTICU'I' FLOOR SWEEPING COMPOSITION Application filed June 12,

It has been common for some time to employ an oily substance, together with a carrying solid, for use as a floor sweeping composition. This type of composition is sprinkled on the floor and is then swept up, carrying with it loose dust particles and transmitting some of its oil to the floor. This residual oil prevents splintering of the fibres where the floor is made of wood and assists in laying dust, but adds a substantial accident hazard due to its tendency to make a floor slippery.

My present invention relates to a composition adapted for sweeping purposes but avoiding the disadvantages and hazards of earlier mixtures. In actual use of my improved composition, a complete elimination of slipping accidents has resulted, the floors are cleaned better, less trouble is experienced from dust, a better wearing surface is pro duced, and the floor remains in an abrasive condition after the compound is swept up.

The improved mixture comprises a of ground feldspar, a smaller proportion of an oil retaining body such as sawdust, and an oil such as paraffin oil. The groundfeldspar possesses a distinct angular cleavage which has proved to be of great utility in this combination. Due to its sharpness it penetrates into the pores of the wood an presents a permanent non-slipping, wear re- Ordinary sand is substanround, and when stepped upon will preventing slipping.

carrying the oil, and forms a softer oil supplying material which is of particular use in picking up the dirt from the floor. The oil which I employ is preferably, although not necessarily, paraffin oil, as this has the property of evaporating to a waxy consistency and thus serving as a binding for the feldspar particles which are left on the floor. It is also cleaner than other oils and assists the abrasive action of the feldspar in cleansing the floor of embedded dirt particles.

The preferred composition is as follows:

Per cent Ground feldspar (to pass 20 to 40 mesh) 80 Sawdust Parafiin oil 15 ing a dust-collecting material mixed with feldspar ground so as to produce crystalline fractures presenting sharp edges.

2. A floor sweeping composition comprising sawdust, paraflin oil, and feldspar ground so as to produce crystalline fractures present- 1 ing sharp edges.

3. A floor sweeping composition comprising by weight about five per cent. sawdust, fifteen per cent. paraffin oil, and eighty per. cent. feldspar ground so as to produce crys- In testimony whereof I have afiixed my signature.
